Highly Pathogenic Avian Influenza Response

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed several findings of the presence of highly pathogenic avian influenza (HPAI) in wild waterfowl in the Atlantic flyways in January 2022. On February 8, 2022 APHIS confirmed H5N1 HPAI in a commercial turkey flock in Dubois County, Indiana. Since then it has been confirmed in multiple states and flock types. The USDA updates the latest HPAI detections on its website.

The first cases of H5N1 in Minnesota were confirmed on March 25, 2022.

The virus has not caused human illness. According to the CDC, Recent Bird Flu Infections in U.S. Wild Birds and Poultry Pose a Low Risk to the Public.

Federal and State partners are working jointly on additional surveillance and testing in the nearby area, following existing avian influenza response plans. During a HPAI event in Minnesota, a response zone is created around the infected premises in order to control movement and establish an area for testing and surveillance protocols to be carried out.

The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in poultry operations, live bird markets, and in migratory wild bird populations. Visit the USDA’s avian health web page for more information.

Commercial poultry producers and backyard flock owners should continue to practice strict biosecurity; most importantly, preventing their birds from exposure to wild waterfowl.

How HPAI cases are identified and announced in Minnesota

There are several steps involved in confirming a poultry flock is positive for a highly pathogenic strain of avian influenza. Here is an outline of the process, which includes timing of public notification:

1. A poultry producer or backyard flock owner notices unexplained death loss or other signs of illness in his/her birds.
2. The individual notifies their veterinarian or an animal health official.
3. Samples are collected from the birds on the premises.
4. Samples are submitted to an approved state laboratory for preliminary testing.
5. State laboratories determine if the samples are positive for an H5 or H7 influenza virus.
   • If samples are positive for an H5 or H7 virus, they are considered as presumptive positives and are forwarded to the National Veterinary Services Laboratory (NVSL) in Ames, Iowa. NVSL is the only laboratory in the United States that is authorized to officially confirm the presence of a HPAI and identify the specific strain of virus.
6. The Minnesota Board of Animal Health will include information on presumptive positive flocks on its website.
7. Once NVSL confirms HPAI, the USDA posts updates on its website.

First and foremost farmers and flock owners need to take care of themselves and their family. The HPAI outbreak may be adding to stress, financial problems, price and marketing uncertainties, household difficulties, and social pressures.

Reporting

Any unexplained illness or increase in mortality, decreased egg production, quiet or depressed birds, respiratory or neurologic (twisted necks or quiet) signs of disease should be investigated. Call your veterinarian to describe the signs in your flock, so together, next steps can be taken. If you do not have a veterinarian, call the Board at 320-231-5170. You may also contact any of our state or federal field staff throughout the state.

Testing

Samples for official avian influenza testing must be collected by an accredited veterinarian or individuals trained and certified as authorized poultry testing agents (APTA). The Minnesota Plan requires 30 pooled tracheal swab samples from each barn when birds are showing signs of disease consistent with influenza. Always collect samples from dead birds before others. Every grower should have enough tracheal swab supplies (BHI tubes and swabs) needed to sample all flocks within your operation. Sample submission forms can be requested from the MPTL and should be submitted to the MPTL in Willmar for testing. When collecting samples in these situations, please call ahead to the MPTL to notify when samples will arrive.

There are remote sample drop sites located in Morrison and Stearns Counties. Producers can get hours of operation and location details from the Minnesota Turkey Growers Association.

When a Minnesota premises is identified with highly pathogenic avian influenza (HPAI), on-the-ground response efforts begin immediately. Animal health officials carry out a number of activities according to protocols established by the U. S. Department of Agriculture in order to manage the disease and reduce any potential risk of its spread. These activities take place not only on the affected premises, but also in two areas around the affected premises called the control area and surveillance zone.

Affected Site

Premises infected with HPAI are placed under quarantine, prohibiting the movement of poultry and poultry products on or off the affected site. The USDA works with infected flock owners to develop a flock plan which includes appraisal and indemnity agreements for depopulation of poultry that remain on the premises. After depopulation of the flock, all carcasses on the affected farms are composted inside of the barns, unless another method of disposal is approved by the response team. This process takes approximately one month to complete.

Control Area

The control area is a 10 km (6.2 miles) zone established around infected flocks. Within this zone, officials work to identify all premises with commercial and backyard poultry. Backyard and commercial flocks are placed under quarantine and cannot move poultry or poultry products on or off their premises. Commercial flocks must undergo surveillance in accordance with USDA protocols. All testing must be negative before quarantines can be lifted.

Backyard flocks will be required to monitor for development of clinical signs and may participate in surveillance testing depending on the situation.

All poultry producers in the control area must comply with stringent biosecurity and permitting protocols in order to move poultry or poultry products off their farms.

Surveillance Zone

The surveillance zone is a 10 km zone surrounding the control area. Animal health officials identify all premises within this zone that have commercial and backyard poultry to provide them with information on HPAI and advise them on biosecurity and close monitoring of their flocks. Surveillance testing of these flocks may occur in accordance with protocols established by the USDA.

If you raise poultry and your farm is located in a Control Area established as a result of a highly pathogenic avian influenza (HPAI) outbreak, you will need a permit from the Board of Animal Health to move your birds and/or poultry related products on or off your farm. Permit requests can be made directly through an EMRS-Gateway Account. For those without a Gateway Account, permit requests can be made by completing the Minnesota Movement Permit Request form.

Before a permit can be issued, a Monitored Premises Status Questionnaire must be submitted to ensure your birds are not displaying signs of HPAI and that you do not have any dangerous connections to an infected farm. Each Questionnaire must be completed for the origin premises on the permit request, be dated within 48 hours of the planned movement, and submitted along with your permit request.

A permit is needed for movement of the following items into or out of a HPAI Control Area:

• Live birds
• Day-old chicks/poults
• Manure/used litter

Blanket permits will be issued for the following items into or out of a HPAI Control Area:

• Eggs and egg products
• Hatching eggs
• Semen
• Feed
• On-farm mortality pick-up (rendering)

Once a permit request has been approved and the required items are verified, a permit will be issued that contains information related to the specific product being moved. All movements made under this permit will need to be captured. Each movement must include the date the move occurred, the amount of product moved, and the negative testing (lab accession) associated with that movement. Anyone with EMRS-Gateway access must enter each movement via the EMRS-Gateway. Those without this access must report movement information to mnairesponse.bah@state.mn.us within 48 hours of the move.

The following general conditions will be listed on the permit and must be followed. Additional details for each of these conditions are explained below, and in the Secure Poultry Supply (SPS) Permit guidance found on the Secure Poultry Supply website. Blanket permits will be valid for 30 days and will require each movement be reported at the time of move.

Example of conditions on a permit:

This is a spreadsheet of companies offering their cleaning and disinfection services for HPAI affected poultry producers. Please contact them directly with questions or to request their services.

Control Area Quarantine Release

Once certain criteria are met, HPAI control areas are released from quarantine. This means that poultry producers and backyard flock owners of non-infected premises are no longer restricted in moving poultry or poultry products off of or onto their farms.

Restocking Process

Affected farms can be cleared for restocking once the following processes are completed:

1. Affected farms complete the cleaning and disinfecting process.
2. Environmental samples are taken and test negative for influenza.
3. Barns complete a 28-day down time.
4. Producer and animal health officials work together to develop restocking plan.

Quarantine Release Process

A producer must go through several steps in order for the quarantine to be lifted. In addition to completing carcass disposal, cleaning and disinfecting, and a 28-day down time period, the following activities must take place before releasing the quarantine on a previously-infected premises:

1. Restock agreement signed.
2. Barns restocked with birds.
3. Three rounds of surveillance testing on birds.
